Bitumen membrane for rest houses & farms in Afif
In short: In Afif (Afif), bitumen membrane for rest houses & farms begins with the roof, falls and drains survey and the flood test; nothing is opened until the position is clear. The centre of Afif sits about 1040 m above sea level (SRTM open elevation data). Published price: Bitumen membrane (per m²), SAR 15–35 per m²; anything else is quoted after the inspection.
Why bitumen membrane differs in Afif
The centre of Afif sits about 1040 m above sea level (SRTM open elevation data). Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.
Team note on Afif: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins..
Picture an owner who has built a rest house or small farm building in the hills, with a flat roof, a water tank on the grounds, and a few rooms that take the weather year after year. Rain comes in heavy bursts, the sun bakes the roof by day, and the owner wants the building to stay dry without constant repairs. Like many owners of properties of this kind, they tend to notice a problem only after the first damp patch appears on a ceiling, so planning the protection before that point makes the work simpler.
Afif sits about 1040 m above sea level, which means its centre is considerably higher than the surrounding lowlands. For a bitumen membrane on a rest house or farm roof, this elevation matters because the site experiences its own weather pattern, with cooler nights and strong daytime heating on exposed flat surfaces. Bitumen membrane costs SAR 15–35 per m², and that range is a useful starting point for budgeting a roof of any size. Owners should also compare it with liquid roof waterproofing at SAR 8–25 per m² and XPS boards at SAR 12–30 per m² when deciding how to protect insulation as well as the structure below.
A sensible sequence begins with a close look at the roof surface, marking every crack and ponding area so the contractor knows exactly where the work is needed. Any cracks should be dealt with first, with crack injection at SAR 40–120 per metre where the gap is narrow and running. The surface should then be cleaned and dried before the membrane goes down, since moisture trapped underneath will cause blistering later. Next, lay the bitumen membrane with careful overlaps and make sure upturns at walls and drains are sealed properly. Finally, record the completed work with photographs and keep a simple note of the materials used, so future maintenance and inspections can be planned with confidence.
Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.
Signs that call for bitumen membrane
The following signs are worth checking before they grow:
- A flat concrete roof that needs waterproofing
- Old rolls that are cracking
Causes we see in the field
- No protection layer — we check this before anything else.
- Seams that were not welded properly.
How we choose the tool in Afif
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
From the first visit to the report
- Preparation: Cleaning, priming and repairs.
- Torch welding: Overlaps are welded and checked.
- Details: Upstands, drains and bases.
- Protection and flood test: Protection is laid after a successful flood test.

The written outputs
The written output: photos of the welds and the flood-test result. The report is numbered and can be checked with its verification code.
Planning the visit in Afif
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
